EMBROlDERlNG-MACH'INE.

SPECIFICATION forming part of Letters Patent No. 563,200, dated June 30,1896. Application filed September 21,1895. Serial No. 563,249. (Nomodel.) Patented in Switzerland January 23, 1895, No. 9,623.

To all whom, it may concern:

Be it known that I, GOTTFRIED MI'JLLER, a citizen of the Republic ofSwitzerland, residing at Herisau, in the Canton of Appenzell,Switzerland, have invented certain new and useful Improvements inEmbroidering-Machines, (for which I have obtained a patent inSwitzerland, No. 9,623, bearing date J anuary 23, 1895,) of which thefollowing is a specification.

This invention has reference to certain improvements in the well-knownSwiss embroidering-machines,by which can be accomplished theembroidering of various designs, which consist of a single or multiplerepetition of a row or line of figures in which, however, the alternateparallel series of rows or lines of figures are transposed so as to beshifted sidewise of but symmetrically with respect to the other rows.If, for instance, each row or line of figures consists of a number ofpattern-figures, the figures of one row or line are located either belowor above and almost intermediately between those of the adjacent row offigures.

By my improved attachment for embroidering-machines the figures of twoadjacent but relatively shifted or transposed parallel rows aresimultaneously embroidered. For this purpose the attachment consists ofa full set of embroidering mechanisms, such as needle-holders, piercers,counter-pressure rails, festooning-forks, &c., and a secondset of theseembroidering mechanisms, which, when the first set has producedarow ofpattern-figures, simultaneously produces a second adjacent butrelatively shifted or transposed parallel row of pattern-figures. Forthe carrying out of this object, the two simultaneously-operatingembroidering mechanisms are transposed or shifted relatively butsubstantiallyparallel and symmetrically with respect to each other.

In the accompanying drawings, Figure 1 represents aside elevation of one-form of attachment to embroidering-machines, by which shifted ortransposed parallel rows of pattern-figures can be produced. Fig. 2 is afront elevation of the two sets of embroidering mechanisms. Fig. 3 showssome of the festooning-forks in side elevation. Fig. 4

represents a broken detail view of the threadseparating device. Fig. 5represents a sectional side elevation of an embroidering-machineembodying my improvements and showing the relative arrangement of theembroidering mechanisms in connection with the main parts of themachine, and in which the festooning-forks, which are locatedimmediately in front of the embroidering-frame, are covered by theactuating mechanisms and are consequently not visible, while thecarriage on the right-hand side of the machine, which is the same in allits details as the carriage on the left-hand side, is omitted. Fig. 6 isa front elevation of the embroidering-machine shown in Fig. 5, theleft-hand half showing especially the arrangement of the operatingmechanisms which are used in the embroidering operation, while theright-hand half omits some of said operating mechanisms to show clearlythe embroidering-frame and fabric to be embroidered, together with thefestooning-forks; and Fig. 7 is a sample of a design as embroidered bymy improved attachment for embroidering-machines.

Similar letters of reference indicate corresponding parts.

The type of machineshown in Figs. 5 and 6 of the annexed drawings, andin connection.

with which my improvements illustrated in Figs. 1 to 4, inclusive, areshown, is well known as Heilmanns embroidering-machine.

H indicates the frame of the machine, and M the carriage, only one ofwhich is shown on the left-hand side, said carriage being reciprocatedon the rail M by means of a belt L, which is guided over rollers l.

0 represents the embroidering-frame,which is connected in the usualmanner, by means of a pantograph, with the original design and isshifted by the same in a plane at right angles to the direction ofmovement of the carriage M.

O O are the fabrics which are stretched upon the embroidering-frame. VIn embroidering-machines heretofore constructed, in which two or morerows 'of needleclamps are arranged in tiers one above the other, it isonly possible to embroider one row of designs upon the fabric at a time,while for every width of fabric only one row of needleclamps on thecarriage and a single set of festooning or looping forks are arranged infront them in upward direction.

of the embroidering-frame. In my invention, however, it is possible toembroider line 1 of pattern-figures a (shown in the lower part of Fig.7) simultaneously with a second row or line of figures 1, whosepattern-figures are identical with those of the line or row 1, butshifted sidewise or laterally of, so as to be arranged intermediatelybetween but parallel and symmetrically with relation to thepattern-figures of the row 1. For the simultaneous embroidering of thetwo lines or rows, each needle-clamp support I) of theembroidering-machine has mounted thereon a row of regularly-arrangedneedle-clamps A, and a second corresponding and parallel row ofneedle-clamps A", which are supported, however, higher than the clampsA, and which are shifted relatively thereto, so as to be locatedapproximately midway between the same. (See Figs. 1 and 2 in addition toFigs. 5 and 6.) In like manner the piercer rail orbracket c is providedwith two sets of piercers G C and the corresponding counter-pressurerail or bracket (Z with two rows of holes D D, of which one row isparallel with and located laterally of, but above and symmetrically to,the other row. The springactuated rear ends of the upper members of allof the needle-clamps A A", which are disposed on one common support orbracket, are so arranged that they are located in one plane and areactuated by one common prolongated cam e. Corresponding to the two rowsof needleclamps of each support or bracket b the festooning-forks, whichserve for the catching of the loops and keeping them open, are likewisearranged in a row so that some of the same will be higher than theothers, as shown in Fig. 3, enlarged, and on a reduced scale in Fig. 6.For this purpose short forks G are made to alternate with higher forks Gthe former corresponding to the rows of embroidering mechanisms A C D,while the latter corresponds to the additional rows of embroideringmechanisms A C and D These festooning-forks are usually arranged infront of the embroidering-frame 0, upon a horizontal bar or row G, whichduring the festooning operation is moved by a suitable mechanismlaterally but in upwardly-inclined or oblique direction, whereby theforks are caused to catch the loops of thread and draw After the loopsof thread are moved upwardly, they are again released as soon as theyare engaged by the next stitches, whereupon the forks are again loweredby the bar or rail G. For producing this movement of the bar or rail Gand the festooning-forks carried thereby, I arrange at the side of theframe a forked operatinglever 9 hung on a pivot g on the frame of themachine, which lever is provided at its rear end with a balance-weightg. lVh en the festooning or looping is to be accomplished,

the forked operating-lever g is moved downwardly through the medium of apin m, that projects laterally from the frame of the carriage, which pinduring the forward motion of the carriage is moved between thecorrespondingly-curved bifurcations of the forked lever, whereby thesame is turned upon its pivot g \Vith this forked lever is pivotallyconnected a system of levers and rods 9 g g*, of which theconnecting-rod g is connected at its lower end with a vertical arm 9connected in turn with the horizontal bar or rail G, whereby an inclinedupward motion is im= parted to the latter through the directing actionof a fixed guide-plate g provided with a cam-groove 9 in which asuitable projec tion on an arm g attached to the vertical arm 9 engages.

For preventing the needle-threads, which are arranged closer together inan embroider= in g-machine provided with myim provements, namely, withthe double set of needle-clamps, than in the embroidering-machinesheretofore in use, having single rows of needleclamps, from gettingmixed up with each other, either during the embroiderin g or thefestooning operation, there is used for every width of fabric, in placeof the usual singlewire cross-rods, a wider frame constituting what maybe termed a thread-separating frame. Said frame folds or swings in adownward direction over the threads during the outward motion of thecarriage, and serves to separate the threads from one another, it beingreturned into its former initial position when the carriage arrivesimmediately in front of the embroidering-frame 0. These thread-separating frames, which are attached to oscillating levers N, that are arrangedon the transverse shaft a of the needle-clamping frame M consist ofparallel wires f f" and regularly-arranged and separated U-shaped wireyokes g, supported by the wire f, said yokes being concaved at theirbridge portions -h, so as to serve as thread-guides for theneedle-clamps A,while those portions of the wire f which are locatedbetween the yokes g form thread-guides for the needle-clamps A". F F(shown in Fig. 4) represent the rows of embroidering-threads, which arepassed through the holes pierced into the fabric to be embroidered.These thread-separating frames are operated so as to be raised by aninclined fork N, which is mounted on the shaft N, said fork abutting,during the forward motion of the carriage, against a pin 71 on the frameof the machine. This pin a passes in between the bifurcations of thefork N, moving the latter and imparting thereby to the oscillating leverN a motion in upward direction, whereby the upper shaft is turned andits movements, through the medium of the connections N N 3 N transmittedto the lower shaft a, so that both of the thread-separating frames aresimultaneously moved back into their upper position.

The oscillating lever N carries a balanceweight or, which accomplishesduring the return motion of the carriage, at the time when the fork Nrecedes from the pin n, the downward motion of the thread-separatingframes upon the rows of threads. The double set of embroiderin gmechanisms, which are relatively shifted or transposed one toward theother so as to be arranged laterally one of the other but ofiset onefrom the other, are operated in the same manner as the singleembroidering mechanisms in embroidering-machines and require no specialdescription of their exact operation, for the same will be readilyunderstood by those skilled in embroidering-machines.

It may be mentioned that the design is not required to be formed offigures that are separated from each other, as is shown at the lowerpart of Fig. 5, for the figures can also be formed into a connecteddesign, as shown at the upper part of Fig. 5. Such a connected design isso formed that the needles of one row of needle-clamps A make, forinstance, the figure a of row 1 or the connecting portion 1', whilesimultaneously the needles for the row of needle-clamps A produce thefigures a or the connections t of row 1. W'ith the present singlearrangement of the embroidering mechanisms each row 1 or 1 is requiredto be embroidered singly and one after the other, while by my improveddouble embroidering mechanisms, which are shifted or transposedlaterally relatively to each other and symmetrically, the two rows orlines of patternfigures can be embroidered simultaneously and parallel,whereby the productive capacity of embroidering-machines of this classcan be doubled in a given time.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In an embroidering-machine, a double set ofembroidering mechanisms, of which the upper set is arrangedsubstantially parallel with and offset symmetrically toward the lowerset, so that both sets form simultaneously two similar butsymmetrically-transposed pattern-figures, substantially as set forth.

2. In embroidering-machines, the combination, with a supporting rail orbracket, of two rows of needle-clamps, of which one row is located aboveand offset symmetrically and substantially parallel with the other, andin which the rear ends of the upper members of the spring-actuatedneedle-clamps are located in one plane, and a cam common to the uppermembers of the spring actuated needleclamps for acting on the rear endsof the same, substantially as set forth.

3. In embroidering-machines, a supporting-rail provided with a doubleset of festooning-forks, some of which alternate with and are higherthan the others, substantially as set forth.

4. In an embroidering-machine, the combination, with a double set ofneedle-clamps, of a corresponding set of thread separating frames orguides composed of two parallel wires, one of which is provided withspaced yokes, substantially as set forth.

5. In an embroidering-machine, the combination, with a double set ofneedle-clamps, of a corresponding set of thread separating frames,composed of two parallel wires, of which one is provided with U-shapedyokes having concaved connecting bridges, substantially as set forth.

In testimony whereof I hereunto sign my name, in the presence of twosubscribing witnesses, this 12th day of August, 1 $95.
